Question
What does DCMU stops?
- PS-I
- Oxidative phosphorylation
- PS-II
- It obliterates chloroplasts.
Hint:
It is also referred to as water-plastoquinone oxidoreductase.
The correct answer is: PS-II
- DCMU refers to 3-(3,4-dichlorophenyl)-1,1-dimethylurea
- DCMU is considered as an algicide or herbicide
- DCMU inhibits carbon dioxide fixation and photosystem II
- DCMU inhibits the QB plastoquinone binding site of photosystem II, which in turn does not allow the flow of electrons from photosystem II to plastoquinone
